APPENDIX C
TECHNICAL REPORT TECHNICAL CONTENT REQUIREMENTS
10. SCOPE
10.1 Scope. This appendix covers the technical content requirements that shall be included
in technical reports when required by the contract or order. This appendix is mandatory only when
data item description DI-MISC-80652 is cited on the DD Form 1423.
.
20. APPLICABLE DOCUMENTS
This section is not applicable to this appendix.
30. DESIGN REPORT
30.1 Design report content. When required by the contract or order, design report content
for applications for which cyclic life requirements are established, shall contain an analysis
demonstrating the adequacy of the design. For heat exchangers designed for submergence pressure,
a design report shall be included. The report shall be in a format to facilitate an independent
review of its content. lt is, therefore, imperative that it be simple to follow, free from ambiguity,
and should contain the following as a minimum:
Description of design requirements such as steady state transient pressures,
a.
temperatures, and external loading
b.
Regions of the component analyzed
c.
Materials used and their mechanical properties
d.
General description of the methods of analysis and assumptions
e.
All reference sources shall be listed.
f.
All computer programs shall be properly identified and described.
Report contains copies of the computer printouts (input and output).
g.
h.
Stresses shall be tabulated for each area of investigation and compared to the allowable
stresses for all stress categories.
i.
Satisfaction of cyclic requirements including stress concentration factors used in the
cyclic analysis.
Manufacturer shall submit calculations demonstrating that the free length of tubes
j.
provided between the double tube sheets is sufficient to comply with 3.14.28.1.1.
